independent repeat signs
I just stumpled over a very basic missing feature in musescore.
I had a hard time notating a simple folk melody. It should be as in the attached pic, but I had to use a lot of volta brackets instead (file attached).
Setting repeat signs inside a bar would be the solution.
Repeats are not the same as bar lines and should be treated independently. Many songs are structured like this, even a lot of chamber music (all those scherzo movements for example).
This is a very common feature in notation, and I see it as a must.
